Hi in postfix I have this configuration in main.cf: smtp_sender_dependent_authentication = yes smtp_sasl_auth_enable = yes smtp_sasl_password_maps = mysql:/etc/postfix/sender_passwd.cf relayhost = [smtp.sendgrid.net]:587 smtp_sasl_security_options = noanonymous
/etc/postfix/sender_passwd.cf: user = user password = pass hosts = host dbname = db query = SELECT CONCAT(email,":",key) FROM users WHERE email = '%s'; In mysql I have unlimited connections, but postfix open +- 10. When I try make a stress test I can send many message but in certain moment I have this error: ar 8 11:06:22 UBMSASENDWEB01 postfix/smtp[5589]: warning: 5D8EC1400CC: *smtp_sasl_password_maps lookup error* Mar 8 11:06:22 UBMSASENDWEB01 postfix/smtp[5589]: 5D8EC1400CC: *local data error while talking to smtp.sendgrid.net[108.168.183.160]* Mar 8 11:06:23 UBMSASENDWEB01 postfix/smtp[5589]: warning: 5D8EC1400CC: smtp_sasl_password_maps lookup error Mar 8 11:06:23 UBMSASENDWEB01 postfix/smtp[5589]: 5D8EC1400CC: to=<mig...@domain.com>, relay=smtp.sendgrid.net[167.89.123.53]:587, delay=6, delays=0.07/0/5.9/0, dsn=4.3.0, status=*deferred (local data error while talking to smtp.sendgrid.net[167.89.123.53])* What can be this?
